DDE Commands Must Be Bracketed for Non-Windows Platform

 Last reviewed: June 1, 1996
Article ID: Q112427
The information in this article applies to:
  • Microsoft FoxPro for MS-DOS, versions 2.5, 2.5a, and 2.5b
  • Microsoft FoxPro for Macintosh, version 2.5b
  • Microsoft Visual FoxPro for Macintosh, version 3.0b

Dynamic data exchange (DDE) commands are not ignored in FoxPro for MS-DOS or FoxPro for Macintosh.

If you execute a DDE command, FoxPro for MS-DOS will produce the error message "Function not implemented." FoxPro for Macintosh will display the error message "Feature not available."

Use the system memory variable _WINDOWS to prevent the error messages from appearing. For example: 

   IF _WINDOWS
      <DDE commands>
   ENDIF
The value of this system memory variable is determined by the version of FoxPro that is executing the code. You cannot use the STORE or = commands to change the value of this variable.

Additional reference words: VFoxMac 3.00b FoxMac FoxDos 2.50 2.50a 2.50b
